The data of 3-year observations of the abundance dynamics of micro-planktonic fraction of Pseudodiaptomus marinus - a new alien copepod for the Black Sea - are presented. Seasonally the first juvenile stages of the species appear in the Sevastopol coastal waters in September. The maximum values were reached at different times: from the end of September to the end of November. Then abundance quickly drops. The presence of nauplius and copepodites in plankton suggests that the new species of copepods successfully reproduces in the Black Sea coastal waters. The total abundance of the invasive species is characterized by low values, which do not exceed in maxima 10 thousand. ind. per m-3. The temperature is assumed to be one of the main factors in the regulation of inter-annual variability in the abundance of the invasive species.
